When mysqldump was used with --innodb-optimize-keys option it produced invalid SQL for cases when there was an explicitly named foreign key constraint which implied an implicit secondary index with the same name. Fixed by detecting such cases and omitting the corresponding secondary keys from deferred key creation optimization. Bug fixed #1081016.

When mysqldump was used with --innodb-optimize-keys and --no-data options, all secondary key definitions would be lost. Bug fixed #989253.

Percona Server was built with YaSSL which could cause some of the programs that use it to crash. Fixed by building packages with OpenSSL support rather than the bundled YaSSL library. Bug fixed #1104977.

Fix for bug #1070856 introduced a regression in Percona Server 5.1.66-14.2 which could cause a server to hang when binary log is enabled. Bug fixed #1162085.

Percona Server would re-create the test database when using rpm on server upgrade, even if the database was previously removed. Bug fixed #710799.

Debian packages included the old version of innotop. Fixed by removing innotop and its InnoDBParser Perl package from source and Debian installation. Bug fixed #1032139.

Percona Server was missing help texts in the MySQL client because the help tables were missing. Bug fixed #1041981.
